Description

Technical Field

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 455,206, filed on March 28, 2023, entitled "Connector Coupling Assembly", the entire disclosure of which is incorporated herein by reference.

[0002] The present disclosure generally relates to connectors, and more particularly to connector couplings.

Background Art

[0003] Medical treatment often involves the infusion of a medical fluid (e.g., saline or a drug) to a patient using an intravenous (IV) catheter, and the IV catheter is generally connected to a fluid source such as an IV bag through a flexible tubing and connector configuration, generally referred to as an "IV set". Often, the tubing or catheter is connected or secured to each other to allow for fluid communication between various portions of the tubing or catheter.

[0004] In some applications, such tubing or catheter may become detached due to improper fixation, and / or may become detached when the coupling is subjected to a force greater than the force for which the coupling was designed to withstand.

When the second biasing element is in the expanded state, the second valve is in the expanded state, and when the second biasing element is in the compressed state, the second valve is in the compressed state.

[0010] In some embodiments, the pull-out force is a force applied to the first connector along its central axis, which extends at least along the length of the first connector.

[0024] Although various configurations of the subject technology will be readily apparent to those skilled in the art from this disclosure, it is understood that the various configurations of the subject technology are presented by way of example only. As will be recognized, other different configurations of the subject technology are possible without departing from the scope of the subject technology, and some of the details thereof are capable of being modified in various other respects. Accordingly, the summary, the drawings, and the detailed description should be regarded as being essentially exemplary and not restrictive.

[0025] The accompanying drawings, which are incorporated in and constitute a part of this specification, are introduced to provide a further understanding and illustrate the disclosed embodiments and serve to explain the principles of the disclosed embodiments together with the description herein.

[Figure 2] A side cross-sectional view of the coupler assembly of FIG. 1, according to various aspects of the present disclosure.

[Figure 5] A side cross-sectional view of the coupler assembly of FIG. 1, according to various aspects of the present disclosure, in which the first connector is connected to the second connector. [Figure 6] A side cross-sectional view of the coupler assembly of FIG. 1, according to various aspects of the present disclosure, in which the first connector is disconnected from the second connector. [Modes for carrying out the invention]

[0027] The disclosed coupler assembly includes a first connector and a second connector. The first connector is configured to connect to the second connector. The coupler assembly may have a first configuration and a second configuration. In the first configuration, the first connector is connected to the second connector. In the second configuration, the first connector is disconnected from the second connector.

[0028] The coupler assembly may be configured to connect a first portion of a pipe to a second portion of the pipe. For example, the first portion of the pipe may be connected to a first connector, and the second portion of the pipe may be connected to a second connector. The first portion of the pipe and / or the second portion of the pipe may also be connected to a patient or a fluid source. In some embodiments, the coupler assembly allows fluid to flow from the first portion of the pipe to the second portion of the pipe. For example, the first connector may be connected to the second connector so as to form a fluid passage through the first and second connectors, allowing fluid to flow from the first portion of the pipe through the first and second connectors. The fluid passage may allow fluid to flow from the second portion of the pipe to the first portion of the pipe through the second and first connectors.

[0029] In some embodiments, the first and second connectors provide a unidirectional fluid flow. For example, when the first connector is connected to the second connector, the fluid may flow from the second connector to the first connector and not from the first connector to the second. In some embodiments, when the first connector is disconnected from the second connector, the fluid flow from the second connector to the first connector is stopped, thereby preventing leakage when the first connector is disconnected from the second connector. In some embodiments, when the first connector is disconnected from the second connector, the first connector is sterilized (e.g., by a sterile cloth or sterilization device) or replaced with a new sterile connector to prevent infection or contamination that may occur if the first connector is reused without sterilization. In some embodiments, the first connector is configured to be disconnected based on a force exceeding a predetermined threshold force. When a force exceeding a predetermined threshold force, such as an uplift force, is applied to the first connector, the first connector can be disconnected from the second connector. The pull-out force may be a force that arises along the longitudinal axis of the first connector. In some embodiments, the pull-out force is generated by strongly pulling or pulling a first portion of the tubing connected to the first connector. Alternatively, the pull-out force applied to the first connector may be generated by strongly pulling or pulling a second portion of the tubing connected to the second connector and / or the second connector.

[0030] In some embodiments, the first connector is configured to reconnect to the second connector when the first connector is disconnected from the second connector. For example, the first connector may be configured to allow reconnection to the second connector after a disconnection event (e.g., due to a disconnection event) when the first connector is disconnected from the second connector.

[0031] The detailed descriptions below are intended to describe various configurations of the subject art and not to represent the only configurations in which the subject art can be implemented. The detailed descriptions include specific details for the purpose of providing a complete understanding of the subject art. However, it will be apparent to those skilled in the art that the subject art can be implemented without these specific details. In some cases, well-known structures and components are shown in block diagrams to avoid ambiguity of the concepts of the subject art. For ease of understanding, similar components are denoted by the same element reference numeral. Reference numerals may be accompanied by subscripts to indicate specific examples of common elements, and the same reference numeral without a subscript is used generically.

[0032] The following description is directed toward connecting medical connectors for administering medical fluids using the disclosed couplers, but it should be understood that this description is merely an example of use and does not limit the scope of the claims. Various embodiments of the disclosed couplers can be used in any application where it is desirable to ensure the connection of various pipes and connectors.

[0033] The disclosed coupler assembly overcomes several challenges found with some conventional couplers. One challenge with some conventional couplers is that some may not be properly secured. Furthermore, some conventional couplers may be designed to release or detach in response to relatively small pull-out forces during use. For example, some conventional couplers may detach in response to pull-out forces when a patient turns over in bed, when a patient presses the tube or line against the bed rail, when a patient is moved to another bed, when a pediatric patient tampers with it, and / or when an adult patient with impaired orientation pulls out their own line. In fact, at the 2017 annual meeting of the Association for Vascular Access (AVA), a 10% detachment rate per 1,000 patients with peripheral IV catheters was reported, which translates to approximately 33 million detachments per year in the United States alone. The use of some conventional couplers is undesirable because accidental or unintentional detachment of tubing, catheters, or connectors can interrupt the administration of medical fluids.

[0034] Accordingly, it is advantageous to provide couplers and coupler / connector assemblies as described herein that enable improved fixation of connectors or fasteners. The couplers and coupler / connector assemblies disclosed herein are constructed as described herein to enable secure retention of a first connector while allowing disconnection after a disconnection event.

Figure 2 is a side cross-sectional view of the coupler assembly of Figure 1 according to various embodiments of this disclosure. Figure 3 is a side cross-sectional view of the first connector of the coupler assembly of Figure 1 according to various embodiments of this disclosure. Figure 4 is a side cross-sectional view of the second connector of the coupler assembly of Figure 1 according to various embodiments of this disclosure. Figure 5 is a side cross-sectional view of the coupler assembly of Figure 1, showing the first connector connected to the second connector, according to various embodiments of this disclosure.

[0036] Referring to Figures 1 to 5, the coupler assembly 100 allows fluid, such as medical fluid, to flow from a fluid source 500 to a patient end 600 by releasably connecting one portion of a pipe or line to another portion of the pipe or line in fluid communication. The coupler assembly 100 may include a first connector 102 and a second connector 140. The first connector 102 may be configured to connect to the second connector 140. In some embodiments, the first connector 102 and / or the second connector 140 are one-way connectors. In the examples depicted, a portion of the pipe can be terminated using connectors / valves such as the first connector 102 and / or the second connector 140. In some embodiments, fluid from the fluid source 500 flows through the coupler assembly 100 to the patient end 600. A cannula or needle can be inserted into the patient at the patient end 600, allowing medical fluid to flow from the fluid source 500 through the coupler assembly 100 into the patient at the patient end 600. In some embodiments, the flow from the fluid source 500 to the patient end 600 is interrupted or blocked by disconnecting the first connector 102 from the second connector 140.

[0037] In some embodiments, the coupler assembly 100 includes a central axis AA, and the first connector 102 and the second connector 140 are connected in series along the central axis AA. The first connector 102 and / or the second connector 140 may allow connection and / or disconnection of pipe material to enable selective fluid communication between them. The central axis AA may extend longitudinally along the length of the first connector 102 and the second connector 140.

[0038] The coupler assembly 100 may have a first configuration (Figure 2) and a second configuration (Figure 6). In the first configuration, the first connector 102 is connected to the second connector 140. In the second configuration, the first connector 102 is disconnected from the second connector 140. In some embodiments, the coupler assembly 100 transitions from the first configuration to the second configuration in response to a disconnection event. Disconnection may even occur when an outward pulling force is applied to the first connector 102, causing axial movement of the first connector 102 relative to the second connector 140. In some embodiments, axial movement of the first connector 102 relative to the second connector 140 occurs when the outward pulling force applied to the first connector 102 exceeds a predetermined threshold force.

[0039] In some embodiments, the first connector 102 is connected to a first portion of a pipe so that the first portion of the pipe can be connected to and / or disconnected from the second connector 140. The first connector 102 may include a first end 101 and a second end 103. The first end 101 may be connected to a pipe (e.g., a first portion of the pipe), and the second end 103 may be configured to connect to the second connector 140. In some embodiments, a portion of the pipe can be connected to or engaged with the first end 101 of the first connector 102. The first connector 102 may be in fluid communication with the pipe via the first end 101 so that fluid can pass through the first connector 102. In some embodiments, the first end 101 may have a flat surface so that a clinician can easily clean and disinfect the first end 101. The first end 101 may be in fluid communication with the second end 103. The first end 101 and the second end 103 may be arranged along the longitudinal length of the first connector 102. For example, the first end 101 and the second end 103 may be arranged along the central axis AA. The first end 101 and / or the second end 103 may include openings to allow the first end 101 and / or the second end 103 to fluidly communicate with one or more elements (e.g., pipes, connectors, valves, collars, fittings, etc.). For example, the first end 101 may be connected to a tube, and the second end 103 may include a channel 134 to allow fluid communication through the first connector 102. The channel 134 may be configured to receive a portion of the second connector 140 (e.g., a connecting portion 150) and secure the second connector 140 to the first connector 102. In some embodiments, the channel 134 includes a distal edge or outer edge 133. The edge portion 133 may be positioned close to the second end portion 103. In some embodiments, when the first connector 102 is connected to the second connector 140, a portion of the second connector 140 (e.g., the connecting portion 150) extends through the second end portion 103.

[0040] In some embodiments, the first connector 102 is configured to connect to the second connector 140 so that fluid flows into the first connector 102 and out through the second connector 140. For example, the first connector 102 may include an inlet (e.g., inlet 115) configured to receive fluid, and the second connector 140 may include an outlet (e.g., outlet 170) configured to allow fluid to exit the second connector 140. In some embodiments, as a result of the first connector 102 being connected to the second connector 140, the inlet (e.g., inlet 115) of the first connector 102 is in fluid communication with the outlet (e.g., outlet 170) of the second connector 140.

[0041] In some embodiments, fluid can exit from or flow through the first connector 102 through a second end 103 located opposite the first end 101. The fluid passage through the first connector 102 may have a linear fluid passage to facilitate flushing and reduce the risk of hemolysis. Optionally, the first connector 102 may include features (e.g., raised features, gripping features) located on its outer surface to allow clinicians to handle or manipulate the first connector 102 more easily. Some embodiments of the first connector 102 may provide a connector that fits with connectors in other parts of the fluid delivery system. The first connector 102 may be substantially cylindrical in shape.

[0042] In some embodiments, the first connector 102 includes an inlet portion 120 disposed adjacent to the first end 101 and a mating portion 130 disposed adjacent to the second end 103. The inlet portion 120 may be configured to connect to a portion of a pipe, allowing the first connector 102 to be in fluid communication with this portion of the pipe. For example, the inlet portion 120 may include an inlet 115 configured to allow fluid to enter the inlet portion 120. The inlet portion 120 may also include a channel 113 for allowing fluid flow within the inlet portion 120. The channel 113 is disposed within the inlet portion 120 and may extend from the first end 101 to the body 116 of the inlet portion 120.

[0043] In some embodiments, the mating portion 130 is located on the opposite side of the inlet portion 120 and is configured to connect to the second connector 140 to secure the first connector 102 to the second connector 140. For example, the mating portion 130 may include one or more grooves 136 configured to receive a portion of the second connector 140 and secure and connect the first connector 102 to the second connector 140, as described below. The grooves 136 may be located adjacent to the second end 103 on the mating portion 130. In some embodiments, the grooves 136 are configured to receive a portion of the second connector 140 and engage with it to secure the first connector 102 to the second connector 140.

[0044] Referring to Figures 2 and 3, the inlet portion 120 may be connected to the paired portion 130 between the first end 101 and the second end 103. The inlet portion 120 may be located close to the first end 101 and may include a channel 113 and an internal space 117. The channel 113 can lead into the internal space 117. For example, the channel 113 may be in fluid communication with the internal space 117. In some embodiments, a portion of the tube is connected to the inlet portion 120 such that this portion of the tube is in fluid communication with the channel 113. As a result of this portion of the tube being in fluid communication with the channel 113, this portion of the tube is also in fluid communication with the internal space 117.

[0045] In some embodiments, the inlet portion 120 includes a body 116 connected to a channel 113. The body 116 may include an internal space 117. The channel 113 may have a diameter smaller than the inner diameter of the body 116. In some embodiments, the volume of the channel 113 is smaller than the volume of the internal space 117 of the body 116. The channel 113 may be in fluid communication with the internal space 117 of the body 116 such that the body 116 (e.g., the internal space 117) is configured to hold a larger volume of liquid than the channel 113.

[0046] The mating portion 130 may be located close to the second end 103 and may include an opening 110, an internal space 132, and a channel 134. The opening 110 may be in fluid communication with the internal space 132 and the channel 134. In some embodiments, the opening 110 is in fluid communication with the internal space 117 of the inlet portion 120. For example, the opening 110 may be in fluid communication with the internal space 117 so that fluid flows from the channel 113 into the internal space 117 and into the opening 110. The fluid can then flow from the opening 110 through the internal space 132 and out of the first connector 102 through the channel 134. In some embodiments, the channel 134 allows fluid to flow out of the first connector 102 and into the second connector 140 when the first connector 102 is connected to the second connector 140. The opening 110 may have a smaller diameter than the channel 134. In some embodiments, the channel 134 has substantially the same diameter as the body 116. In some embodiments, the first connector 102 is formed by connecting the inlet portion 120 to the mating portion 130. Alternatively, the first connector 102 is formed from a single piece.

[0047] Referring to Figure 3, the first connector 102 may include a valve 104. The valve 104 may be disposed within the internal space 117 of the body 116. In some embodiments, the valve 104 may extend at least partially into the mating portion 130. For example, the valve 104 may extend from the inlet portion 120 (e.g., the internal space 117) into the opening 110 of the mating portion 130. In some embodiments, the valve 104 is configured to seal the opening 110 to prevent fluid from flowing out (e.g., leaking) from the first connector 102. For example, the valve 104 may be configured to seal the opening 110 to block fluid communication between the internal space 117 of the inlet portion 120 and the internal space 132 of the mating portion 130. In some embodiments, the opening 110 is sized and shaped to match the contour of the valve 104 so that the valve 104 can seal the opening 110. The valve 104 may have any shape configured to seal the opening 110. In some embodiments, the first connector 102 allows for unidirectional flow of fluid. For example, the first connector 102 and / or valve 104 may allow fluid to flow out of the opening 110 but not into the opening 110.

[0048] The valve 104 may have a first end 105 and a second end 107. The second end 107 may be located opposite the first end 105. In some embodiments, the first end 105 and the second end 107 have substantially planar surfaces. The surface of the first end 105 may be substantially parallel to the surface of the second end 107. In some embodiments, the length and / or width of the surface of the second end 107 is smaller than the length and / or width of the surface of the first end 105.

[0049] The valve 104 may be connected to a biasing element 119. In some embodiments, the valve 104 is connected to the biasing element 119 at a first end 105. The biasing element 119 may be a spring or a spring-like structure that allows the biasing element 119 to be in a compressed or expanded state. The biasing element 119 may be disposed within an internal space 117. In some embodiments, the biasing element 119 is disposed in close proximity to the first end 101. The biasing element 119 may be disposed within the body 116 such that the biasing element 119 is located within the internal space 117. In some embodiments, the biasing element 119 has a first end 121 disposed in close proximity to the channel 113 and a second end 123 disposed in close proximity to the valve 104. The valve 104 may be connected to the biasing element at the second end 123. For example, the second end 123 may be connected to the first end 105 of the valve 104. The first end 121 may be connected to the distal end 111 of the channel 113. For example, the channel 113 may become an internal space 117 at its distal end 111. In some embodiments, a biasing element 119 is connected to the distal end 111 of the channel 113.

[0050] The biasing element 119 may have a compressed state and an expanded state. For example, the biasing element 119 may be configured to be compressed (e.g., shortened in length) or expanded (e.g., lengthened in length). The biasing element 119 may be biased to be in an expanded state. In the compressed state, the second end 123 is positioned close to the first end 121 and the distal end 111 of the channel 113. In the expanded state, the second end 123 may be positioned away from the first end 121. Since the valve 104 is connected to the second end 123, in the compressed state, the valve 104 is positioned closer to the first end 121 and the distal end 111 compared to when the biasing element 119 is in an expanded state. In some embodiments, when the biasing element 119 is in an expanded state, the valve 104 is positioned away from the first end 121 and at least partially positioned within the opening 110. In some embodiments, the valve 104 extends at least partially through the opening 110 to seal the opening 110. The valve 104 is at least partially located within the opening 110 and extends partially through it, thereby sealing the opening 110 from the internal space 117. For example, the biasing element 119 may be in an extended position, resulting in the valve 104 being at least partially located within the opening 110. The valve 104 located within the opening 110 prevents the inlet portion 120 (e.g., channel 113 and internal space 117) from fluid communication with the mating portion 130 (e.g., internal space 132 and channel 134).

[0051] In some embodiments, when the biasing element 119 is in an expanded state, the valve 104 is in an expanded state and extends at least partially through the opening 110. In some embodiments, when the valve 104 and the biasing element 119 are in an expanded state, the second end 107 is positioned through the opening 110. For example, when the valve 104 and the biasing element 119 are in an expanded state, the opening 110 may be positioned between the first end 105 and the second end 107.

[0052] In some embodiments, when the valve 104 is pushed or pressure / force is applied to the valve 104 through another structure, the biasing element 119 becomes compressed, resulting in fluid communication between the mating portion 130 and the inlet portion 120. When the pressure / force is removed from the valve 104, the biasing element 119 can return to an expanded state, resulting in the valve 104 being positioned at least partially within the opening 110, thereby preventing the inlet portion 120 from being in fluid communication with the mating portion 130.

[0053] Referring to Figures 1 to 4, the first connector 102 may be configured to connect to the second connector 140. The second connector 140 may include a connecting portion 150 and an outflow portion 160. The connecting portion 150 may be configured to connect to the outflow portion 160. In some embodiments, the connecting portion 150 and the outflow portion 160 form a single structure, thereby forming the second connector 140.

[0054] In some embodiments, the second connector 140 is connected to a second portion of a pipe so that the second portion of the pipe can be connected to and / or disconnected from the first connector 102. The second connector 140 may include a first end 151 and a second end 153. The first end 151 may be configured to connect to the first connector 102, and the second end 153 may be connected to a pipe (e.g., a second portion of the pipe). In some embodiments, a portion of the pipe can be connected to or engaged with the second end 153 of the second connector 140. The second connector 140 may be fluid-connected to the pipe via the second end 153 so that fluid can pass through the second connector 140. In some embodiments, the first end 151 may have a flat surface so that a clinician can easily clean and disinfect the first end 151. The first end 151 may be fluid-connected to the second end 153. The first end 151 and the second end 153 may be arranged along the longitudinal length of the second connector 140. For example, the first end 151 and the second end 153 may be arranged along the central axis AA. The first end 151 and / or the second end 153 may include openings to allow the first end 151 and / or the second end 153 to be in fluid communication with one or more elements (e.g., pipes, connectors, valves, collars, fittings, etc.). For example, the first end 151 may include an opening 156, and the second end 153 may be connected to a tube to allow fluid communication through the second connector 140.

[0055] In some embodiments, fluid can exit from or flow through the second connector 140 via a second end 153 located opposite the first end 151. The fluid passage through the second connector 140 may have a linear fluid passage to facilitate flushing and reduce the risk of hemolysis. Optionally, the second connector 140 may include features (e.g., raised features, gripping features) located on its outer surface to allow clinicians to handle or manipulate the second connector 140 more easily. Some embodiments of the second connector 140 may provide a connector that conforms to connectors in other parts of the fluid delivery system. The second connector 140 may be substantially cylindrical in shape.

[0056] In some embodiments, the second connector 140 includes a connecting portion 150 disposed adjacent to the first end 151 and an outflow portion 160 disposed adjacent to the second end 153. The outflow portion 160 may be connected to a portion of a pipe to enable the second connector 140 to communicate fluid with this portion of the pipe and, through the portion of the pipe, with the patient. For example, the outflow portion 160 may include a channel 164 for enabling fluid flow within the outflow portion 160. The channel 164 is disposed within the outflow portion 160 and may extend to the length of the outflow portion 160. The channel 164 may include an outlet 170. The outlet 170 may be located at the distal end of the channel 164 and may be located adjacent to the second end 153.

[0057] In some embodiments, the connecting portion 150 is located on the opposite side of the outflow portion 160 and is configured to connect to the first connector 102 to secure the first connector 102 to the second connector 140. For example, the connecting portion 150 may be configured to connect to a part of the first connector 102 to secure and connect the first connector 102 to the second connector 140, as described below. In some embodiments, the connecting portion 150 is sized and shaped to be received by the first connector 102 and located within the first connector 102, for example, within a mating portion 130. For example, the mating portion 130 may be configured to receive and secure the connecting portion 150 in order to secure the second connector 140 to the first connector 102. In some embodiments, the mating portion 130 receives the connecting portion 150 so that it extends through the second end 103.

[0058] In some embodiments, the connecting portion 150 includes a channel 164 and a tube 162. The channel 164 may extend through the tube 162. The channel 164 may include a proximal end 163 which may include an opening 176. The channel 164 may also include an outlet 170, which may be located on the opposite side of the opening 176 and the proximal end 163. The channel 164 may be configured to allow fluid communication between the outlet 170 and the opening 176, such that fluid entering the channel 164 at the opening 176 (e.g., from the first connector 102) flows through the channel 164 and out through the outlet 170. The tube 162 may be configured to receive and connect to a portion of a pipe (e.g., a second portion of a pipe). In some embodiments, the tube 162 includes a groove 169 located on the inner surface of the tube 162. The groove 169 may be configured to assist in securing the portion of the pipe within the tube 162. For example, a portion of the pipe material may be inserted into the tube 162, and the groove 169 may be configured to help prevent the portion of the pipe material from being inadvertently removed from or disconnected from the second connector 140.

[0059] The connecting portion 150 may be positioned closer to the first end 151 compared to the outflow portion 160. The connecting portion 150 may include an opening 156. In some embodiments, the opening 156 is positioned closer to the first end 151. The connecting portion 150 may include an internal space 154 disposed within the connecting portion 150. In some embodiments, the connecting portion 150 includes a biasing element 152 and a valve 165 disposed within the internal space 154. In some embodiments, the valve 165 is positioned closer to the first end 151 compared to the biasing element 152. The biasing element 152 may be a spring connected to the end of the valve 165. The biasing element 152 may be a spring or spring-like structure that allows the biasing element 152 to be in a compressed or expanded state.

[0060] The biasing element 152 may have a first end 153 and a second end 155. The first end 153 of the biasing element 152 may be positioned closer to the first end 151 than to the second end 155. The biasing element 152 may be connected to a valve 165. In some embodiments, the valve 165 is connected to the first end 153 of the biasing element 152. The valve 165 may have a first end 161 and a second end 167. The second end 167 may be positioned on the opposite side of the first end 161. In some embodiments, the first end 161 and the second end 167 have substantially planar faces or surfaces. The surface of the first end 161 may be substantially parallel to the surface of the second end 167. In some embodiments, the length and / or width of the surface of the first end 161 is smaller than the length and / or width of the surface of the second end 167. In some embodiments, the valve 165 is connected to the biasing element 152 at a second end 167.

[0061] In some embodiments, when the biasing element 152 is in an expanded state, the valve 165 is in an expanded state and extends at least partially through the opening 156. In some embodiments, when the valve 165 and the biasing element 152 are in an expanded state, the first end 161 is positioned through the opening 156. For example, when the valve 165 and the biasing element 152 are in an expanded state, the opening 156 may be positioned between the first end 161 and the second end 167.

[0062] In some embodiments, the channel 164 extends into the connecting portion 150 through the outflow portion 160. For example, the channel 164 may extend into the internal space 154 from a region adjacent to the second end 153. In some embodiments, the opening 176 is located within the internal space 154. The second end 155 of the biasing element 152 may be connected to the channel 164 such that the opening 176 is located adjacent to the second end 155.

[0063] The biasing element 152 may have a compressed state and an expanded state. For example, the biasing element 152 may be configured to be compressed (e.g., shortened in length) or expanded (e.g., lengthened in length). The biasing element 152 may be biased to be in an expanded state. The biasing element 152 may be substantially the same as the biasing element 119. In some embodiments, the biasing element 152 and the biasing element 119 are the same. Alternatively, the biasing elements 119 and 152 may have different lengths, different stiffnesses, or be made from different materials.

[0064] In the compressed state, the first end 153 is positioned close to the second end 155 and the opening 176 of the channel 164. In the expanded state, the first end 153 may be positioned away from the second end 155. Since the valve 165 is connected to the first end 153, in the compressed state, the valve 165 is positioned closer to the second end 155 and the opening 176 compared to when the biasing element 152 is expanded. In some embodiments, when the biasing element 152 is expanded, the valve 165 is positioned away from the second end 155 and at least partially positioned within and / or through the opening 156. By positioning the valve 165 at least partially within the opening 156, the opening 156 is sealed, thereby preventing any fluid from flowing into or out of the opening 156 (e.g., leaking). For example, the biasing element 152 may be in an extended position, resulting in the valve 165 being positioned at least partially within the opening 156. The valve 165 being positioned within and / or through the opening 156 seals the opening 156, preventing the fluid from entering or leaving the second connector 140 (e.g., leaking). In some embodiments, the opening 156 is sized and shaped to match the contour of the valve 165 so that the valve 165 can seal the opening 156. The valve 165 may have any shape configured to seal the opening 156. In some embodiments, the second connector 140 allows for unidirectional flow of fluid. For example, the second connector 140 and / or the valve 165 may allow fluid to flow into the opening 156 but not out of it.

[0065] In some embodiments, the first end 153 of the biasing element 152 is connected to a valve 165. The valve 165 may be disposed within the internal space 154 and may be configured to extend at least partially through the opening 156. In some embodiments, the valve 165 is configured to seal the opening 156 when the biasing element 152 is in an expanded state. For example, the valve 165 may be disposed entirely within the opening 156 and extend at least partially through the opening 156 to seal the opening 156.

[0066] In some embodiments, when the valve 165 is pushed or pressure / force is applied to the valve 165 through another structure, the biasing element 152 becomes compressed, as a result allowing fluid to flow into and / or out of the opening 156. When the pressure / force is removed from the valve 165, the biasing element 152 can return to an expanded state, as a result of the valve 165 being positioned at least partially within the opening 156, thereby sealing the opening 156 and preventing fluid from flowing into and / or out of the opening 156 (e.g., leaking).

[0067] In some embodiments, when the biasing element 152 is compressed and the valve 165 is not sealing the opening 156, the opening 156 is in fluid communication with the channel 164. For example, fluid flows into the opening 156 and into the internal space 154. Fluid can then flow from the internal space 154 into the channel 164 through the opening 176. The fluid can then flow through the channel 164 and through the tube 162 and groove 169 into the pipe section connected to the output section 160. As a result of the biasing element 152 being in the expanded position, the valve 165 seals the opening 156, and the opening 156 is no longer in fluid communication with the channel 164.

[0068] Referring to Figure 2, the first connector 102 may be configured to connect to the second connector 140. In some embodiments, connecting the first connector 102 to the second connector 140 results in the inlet 115 being in fluid communication with the outlet 170. For example, connecting the first connector 102 to the second connector 140 results in the internal space 117 being in fluid communication with the internal space 154. In some embodiments, connecting the first connector 102 and the second connector 140 results in the mating portion 130 receiving most or at least part of the connecting portion 150. For example, the mating portion 130 may include a channel 134 configured to receive and secure the connecting portion 150. The mating portion 130 may include one or more grooves 136 configured to secure the connecting portion 150 within the mating portion 130.

[0069] The mating portion 130 may be configured to secure the second connector 140 to the first connector 102 so as to prevent the second connector 140 from being unintentionally disconnected from the first connector 102. For example, the mating portion 130 may be configured to secure the second connector 140 by friction-fitting the connecting portion 150 into the mating portion 130. In some embodiments, the second connector 140 is connected to and secured to the first connector 102 by friction-fitting or snap-fitting the connecting portion 150 into the mating portion 130. The connecting portion 150 may be disposed and secured within the mating portion 130 via snap-fitting, friction-fitting, magnets, male and female threads, adhesive, or any other type of fastening element. For example, the connecting portion 150 may be disposed and secured within the mating portion 130 by snap-fitting, friction-fitting, or by screw-engaging the connecting portion 150 to the mating portion 130.

[0070] The groove 136 may assist in securing the connecting portion 150 within the mating portion 130. In some embodiments, the connecting portion 150 may be inserted through the channel 134 such that the opening 156 of the second connector 140 is positioned close to the opening 110 of the first connector 102. In some embodiments, the first connector 102 is connected to the second connector 140, and the opening 110 contacts or abuts against the opening 156.

[0071] The connecting portion 150 may include a ring 157 configured to prevent the second connector 140 from being further inserted into the mating portion 130. For example, the ring 157 may be a protruding ring around the connecting portion 150 that can abut against the outer edge (e.g., 133) of the channel 134 when the first connector 102 is connected to the second connector 140. The ring 157 may prevent the second connector 140 from being inserted through the opening 110 of the first connector, and / or prevent the first connector 102 from being inserted through the opening 156 of the second connector.

[0072] When the first connector 102 is not connected to the second connector 140, valve 104 can enter and extend through opening 110, and valve 165 can enter and extend through opening 156. In some embodiments, both valve 104 and valve 165 can be in an expanded state when the corresponding biasing elements 119 and 152 are in an expanded state. As a result of valve 104 being in an expanded state, valve 104 will seal opening 110 by entering and extending through it. As a result of valve 165 being in an expanded state, valve 165 will seal opening 156 by entering and extending through it. As a result of biasing elements 119 and 152 being in a compressed state, the corresponding valves 104 and 165 will be in a compressed state. When valve 104 is in a compressed state, valve 104 no longer seals opening 110, and when valve 165 is in a compressed state, valve 165 no longer seals opening 156. In some embodiments, when the first connector 102 is disconnected from the second connector 140 (for example, when the coupler assembly 100 is in the second configuration), valve 104 seals opening 110 and valve 165 seals opening 156, resulting in no fluid leakage from openings 110 and 156. Valves 104 (and biasing element 119) and 165 (and biasing element 152) can transition from an expanded state to a compressed state by the force applied to valves 104 and 165, respectively.

[0073] In some embodiments, when the first connector 102 is connected to the second connector 140 (for example, when the coupler assembly 100 is in the first configuration), valve 104 exerts force on valve 165, resulting in valve 104 (and biasing element 119) being compressed, and valve 165 exerts force on valve 104, resulting in valve 165 (and biasing element 152) being compressed. In other words, when the first connector 102 is connected to the second connector 140, valves 104 and 165 exert force on each other, resulting in both valves 104 and 165 being compressed, allowing opening 110 to communicate fluidly with opening 156.

[0074] In some embodiments, connecting the first connector 102 to the second connector 140 results in the opening 110 being in contact with or positioned close to the opening 156. As valve 104 extends through the opening 110 and valve 165 extends through the opening 156, when the opening 110 is in contact with or positioned close to the opening 156, for example when the first connector 102 is connected to the second connector 140, valves 104 and 165 can exert force (e.g., pressure) on each other, resulting in valves 104 and 165 being compressed. As a result of valves 104 and 165 being compressed, the openings 110 and 156 are no longer sealed, thus allowing fluid to flow out of the opening 110 and into the opening 156.

[0075] In practice, the second connector 140 is connected to the first connector 102 by inserting the connecting portion 150 into the mating portion 130. The connecting portion 150 can be inserted into the mating portion 130 until the opening 156 abuts against the opening 110 and / or until the outer edge (e.g., edge 133) of the channel 134 abuts against the ring 157. As a result of the opening 156 abutting against the opening 110, the valve 104 extends at least partially through the opening 110 and the valve 165 extends at least partially through the opening 156, so the valve 104 contacts the valve 165. As a result of the valve 104 contacting the valve 165, each exerts force or pressure on the other. Since valve 104 is connected to biasing element 119 and valve 165 is connected to biasing element 152, when force or pressure is applied, valves 104 and 165 can each transition from an expanded state to a compressed state, and as a result, the corresponding openings 110 and 156 are no longer sealed. Since opening 110 abuts against opening 156 and openings 110 and 156 are no longer sealed by the corresponding valves 104 and 165, opening 110 can be in fluid communication with opening 156. In some embodiments, as a result of opening 110 being in fluid communication with opening 156, fluid can flow through openings 110 and 156 from the first connector 102 to the second connector 140.

[0076] Referring to Figure 5, as a result of the opening 110 being in fluid communication with the opening 156, a fluid passage (indicated by an arrow in Figure 5) is formed between the first connector 102 and the second connector 140. For example, when the first connector 102 is connected to the second connector 140, the opening 110 can be in fluid communication with the opening 156, and as a result, a fluid passage is formed between the first connector 102 and the second connector 140. The fluid passage can be formed when the coupler assembly 100 is in the first configuration (for example, when the first connector 102 is connected to the second connector 140). In the first configuration, fluid can flow into the first connector 102 through the inlet 115. The fluid can then flow around the biasing element 119 and valve 104, which may be in a compressed state within the internal space 117 of the body 116, and through the opening 110. The fluid then enters the internal space 154 through opening 110 and opening 156, and can flow around the valve 165 and biasing element 152. The fluid flows from the internal space 154 into opening 176, through channel 164, and out through outlet 170 into a portion of the tubing connected to the outflow section 160.

[0077] Figure 6 is a side cross-sectional view of the coupler assembly of Figure 1, in which the first connector is disconnected from the second connector, according to various embodiments of this disclosure.

[0078] Referring to Figure 6, the coupler assembly 100 may be configured as in the second configuration. In the second configuration, the first connector 102 is disconnected from the second connector 140. In the second configuration, the biasing element 119 and valve 104 and valve 165 and biasing element 152 return to their biased extended state, interrupting the fluid passage between the first connector 102 and the second connector 140. In some embodiments, as a result of the biasing element 119 and valve 104 returning to the extended state, the opening 110 is sealed, preventing fluid from flowing into / out of the first connector 102. In some embodiments, as a result of the biasing element 152 and valve 165 returning to the extended state, the opening 156 is sealed by valve 165, preventing fluid from flowing into / out of the second connector 140. The coupler assembly 100 can transition from the first configuration to the second configuration by disconnecting the first connector 102 from the second connector 140.

[0079] In some embodiments, the first connector 102 is configured to be disconnected from the second connector 140 by a break event caused by a pull-out force. For example, a pull-out force (e.g., force F) can be applied to the first connector 102 either directly or indirectly, such as by being applied to a pipe connected to the first connector 102. The pull-out force can move the first connector 102 axially away from the second connector 140 along the central axis AA, thereby disconnecting the first connector 102 from the second connector 140.

[0080] In some embodiments, the first connector 102 is disconnected from the second connector 140 when a force F exceeds a predetermined threshold force. For example, if the force F is less than the predetermined threshold force, the first connector 102 may not be disconnected from the second connector 140. The predetermined threshold force prevents accidental or inadvertent disconnection based on small forces or small movements. The predetermined threshold force may be based on the flexibility and / or rigidity of the mating portion 130 and / or groove 136. For example, the higher the rigidity of the mating portion 130 and / or groove 136, the higher the predetermined threshold force. In some embodiments, the mating portion 130 includes grooves 136 located at various positions within the channel 134 to increase the frictional force of the connecting portion 150 (and the second connector 140) for the purpose of preventing accidental disconnection of the connecting portion 150 from the first connector 102. For example, the presence of multiple grooves 136 results in multiple positions or snap positions for fixing the connecting portion 150 within the mating portion 130. Having multiple positions allows for varying forces to be required to disconnect the second connector 140 from the first connector 102. Multiple positions and varying forces may be required depending on the desired use of the coupler assembly 100. In some embodiments, if the pull-out force exceeds a predetermined threshold force, the mating portion 130 and / or grooves 136 may fail to hold the connecting portion 150 within the mating portion 130, thereby enabling the first connector 102 to be disconnected from the second connector 140.

[0081] In some embodiments, the predetermined threshold force is approximately 1.8 kilograms (4 pounds (lb)). The predetermined threshold force may range from approximately 0.45 kg (1 lb) to approximately 3.6 kg (8 lb), approximately 1.36 kg (3 lb) to approximately 3.18 kg (7 lb), approximately 1.8 kg (4 lb) to approximately 2.7 kg (6 lb), or greater than approximately 3.6 kg (8 lb). For example, the patient may have a needle / catheter inserted into their skin, and the needle / catheter may be connected to a first connector 102 or a second connector 140. The patient may walk away from the infusion pump or accidentally pull on a fluid line connected to the first connector 102 or the second connector 140, with a force exceeding 1.8 kg (4 lb), causing the first connector 102 to automatically release or disconnect from the second connector 140, effectively closing the fluid passage between the first connector 102 and the second connector 140 as described herein.

[0082] In some embodiments, when the first connector 102 is disconnected from the second connector 140, the user sterilizes the first connector 102 and reconnects the first connector 102 to the second connector 140 by reinserting the connecting portion 150 into the mating portion 130. In some embodiments, the user can sterilize the first connector 102 and / or the second connector 140. As a result of reconnecting the first connector 102 to the second connector 140, the coupler assembly 100 transitions from the second configuration to the first configuration.
